The global shipping industry is facing renewed uncertainty as the United States and China roll out port fees targeting each other’s vessels, intensifying tensions in the ongoing trade conflict between the world’s two largest economies. Analysts warn that these tit-for-tat port fees could “distort global freight flows,” impacting a wide range of goods, from crude oil to holiday toys.

Background: Trade War Escalates on the High Seas

The new port fees mark a significant escalation in US-China trade tensions. Following China’s announcement of expanded rare earth export controls, US President Donald Trump threatened to impose triple-digit tariffs on Chinese goods, signaling a potential return to a full-scale trade war.

In response, both nations have implemented measures targeting shipping companies:

• China introduced special charges on US-owned, US-operated, US-built, or US-flagged vessels, exempting Chinese-built ships and vessels entering Chinese shipyards for repair.
• The US implemented similar port fees targeting China-linked ships, a policy designed to strengthen US shipbuilding and reduce China’s influence in global maritime logistics.

Athens-based shipping analysts at Xclusiv Shipbrokers warn that this “tit-for-tat symmetry locks both economies into a spiral of maritime taxation” with potential ripple effects for global trade.

Impact on Shipping Companies and Global Trade

Major container shipping lines, including COSCO, Maersk, Hapag-Lloyd, and CMA CGM, are adjusting operations to minimize exposure. COSCO is expected to bear nearly half of the anticipated $3.2 billion in US port fees in 2026. Companies are re-routing vessels and attempting to offload cargoes to alternate destinations.

Independent analysts, such as Ed Finley-Richardson, note that some US shipowners with non-Chinese vessels are exploring ways to divert cargo mid-voyage to avoid fees, although these reports remain unconfirmed.

Additionally, China has imposed sanctions on US-linked subsidiaries of South Korean shipbuilder Hanwha Ocean, citing support for US trade investigations. Shares of Hanwha Ocean fell nearly 6% following the announcement.

Port Fees and Environmental Policy Intersections

The latest tensions also intersect with global environmental initiatives. In reprisal for China curbing exports of critical minerals, the Trump administration threatened 100% tariffs on Chinese goods and new export controls on software by November 1.

US officials further warned that countries supporting the IMO (International Maritime Organization) greenhouse gas reduction plan could face sanctions, port bans, or punitive fees. China has publicly backed the IMO environmental measures, signaling a growing trend of the “weaponization” of both trade and environmental policies.

Athens-based Xclusiv analysts commented, “Shipping is no longer a neutral conduit of global commerce; it has become a direct instrument of statecraft.”

Scope of the Impact on Global Shipping

According to industry reports:

• Oil Tankers: China’s port fees may affect approximately 15% of global oil tanker capacity.
• Crude Tankers and Container Ships: Jefferies analyst Omar Nokta estimates 13% of crude tankers and 11% of container vessels could be impacted.
• LPG Carriers: Vortexa data shows 45 very large gas carriers (VLGCs) subject to China’s fees, representing 11% of the total fleet.

These measures threaten to disrupt global supply chains, increase shipping costs, and delay deliveries of essential goods.

Tit-for-Tat Moves and Industry Reactions

The shipping industry has faced intense scrutiny and operational challenges:

• Trade officials in the US reduced initial fee proposals after lobbying from agriculture, energy, and shipping sectors.
• Exemptions and carve-outs were made for long-term charterers of China-operated vessels carrying US ethane and LPG, deferring fees until December 10.
• Shipping lines have shifted vessels to minimize exposure and explore alternative routes.

Despite these measures, analysts warn that supply chain disruptions and price increases are likely to continue, especially if both nations escalate further.

Global Implications

The port fees reflect a broader strategic confrontation between the US and China:

• The move challenges the neutrality of maritime trade and positions shipping as a tool of geopolitics.
• Global industries, from energy to consumer goods, could face higher costs and delays.
• Investors and trading companies are closely monitoring developments, as the situation could affect global logistics, port operations, and freight rates.

Shipping experts caution that unless diplomatic solutions are found, these measures may represent the beginning of a prolonged maritime trade war, with repercussions for the global economy.
